What are the impacts of using conditions on the service life of diesel vehicles?
(1) Fuel quality. The more harmful substances and dust in diesel fuel, the higher the auto ignition point, and the lower thermal efficiency, will deteriorate the power and economy of the diesel engine, and will also aggravate the wear of crankshaft connecting rod parts. Sulfides in fuel have a corrosive effect on the parts.
(2) Lubricant material quality. In order to ensure that diesel vehicles are well lubricated, lubricants with suitable viscosity should be selected according to changes in season and temperature.
(3) Road conditions. Poor roads have increased the impact on the deformation of diesel automobile basic parts (such as cylinder block, transmission case, rear axle case and differential case, etc.), which has damaged the correct fitting position between parts and shortened the service life. For example, when the squareness error of the cylinder axis relative to the crankshaft shaft joint is 0.18 mm in length of 200 mm, the service life of the diesel engine will be shortened by 30%. At the same time, due to frequent changes in the driving speed of diesel vehicles, the wear of mechanical parts, clutch followers and springs, transmission gears, brake drums and shoes are aggravated.
(4) climatic conditions. If the temperature is too high or too low, the wear of the parts will increase.
(5) Maintenance quality. Diesel vehicles must be timely and in accordance with the requirements of lubrication, inspection, adjustment, fastening and other work, there should be timely troubleshooting, otherwise it will make the performance of parts, wear, increased, resulting in diesel engine power and economic deterioration.
